Keep diaries of your 20" wheel and under build of bikes here.
Paul decided that the kid bike build off was right up his alley. No limitations on frame mods.
So I rounded up some parts and headed over to his house today to see what he could put together.
I brought the remnants of a BMX bike that I found in the neighborhood a few months ago, a coaster brake wheel that a guy at a flea market gave me and Paul, and a 16" Schwinn chopper bike that my grandson had outgrown.
Paul decided that for this bike build he needed to become "Uncle Shrink" instead of "Uncle Stretch", so he went into shrink mode.
The first step was to determine how a 20" frame would line up on his jig - since it was setup for building 26" bikes.
Then he decided on the size pipe he wanted to use for the frame and began work.
After doing some work with his pipe bender the top tubes went into place.
Once the top tubes were in place the seat tube came next.
The next step was to graft on the rear frame section from a 24" girl's mountain bike.
Once the rear section was in place we threw on the 20" wheels, a seat, and the handlebars that came on the Schwinn chopper and here are the results of today's build.
Paul said tomorrow will be spent doing some additional clean up on the welds, throwing on his signature black paint job, and installing the crank and chain. So if all goes as planned this build could be in the bag by tomorrow.
So it looks like this will be another quick build by Uncle Stretch - I mean Uncle Shrink.

As you can imagine, neither of us had a lot of extra 20" bike parts laying around.
So blackwalls was the best we could come up with.
Once the crank and chain are in place and the paint job is done it will look like mini me for sure.
Ok I might be stuck on a design.....but when was the last time you saw a kid ridding a miniture 1938 Colson around your neighborhood.
Is everybody finished building yet?
The hardest part was getting the Schwinn Stingray Chopper bike away from my grandson.
He put up quite a fight and he was laying there crying like a baby when I tossed it into the back of my Trailblazer and took off.
Hey, we needed the front end for the build off .... what could I say.
Just kidding. He actually got a new 20" BMX for Christmas so this one was just a left over and my daughter was happy to get it out of her garage.
The funny thing is the bike came with an 18" wheel on the front and a wide 16" on the back and the neck on those chopper bikes are raked like crazy, so the front fork actually has enough room to easily run a 24" wheel and I think even a 26" wheel would fit.
Also, it has a 5" neck tube, so it would work on a lot of adult sized bikes.
that is really cool it has an early motocross motorcycle look to it
Paul got busy again today and finished up the paint and put the mini clone together.
So here's a few shots of the finished product.
Once I get back over to his place we'll take some riding pictures or maybe a video.
Hummm, two good sized brothers trying to ride a mini clone bike. Should make for some interesting pictures.
